Project Description:
Braiding is a high rate fabrication method of structural composites for applications ranging from bridges to high-performance bike frames. It produces near-net-shape structures by interlacing continuous fibers into a pre-form architecture. Braided composites are created by impregnating the braid pre-form in a matrix material. Braiding is an attractive manufacturing method since a variety of matrix, fiber and braid geometries can be used to tailor mechanical properties. BC offer improved impact resistance and energy absorption characteristics over conventional laminated composite structures.
A major challenge with braided composites is the measurement and prediction of failure. The difficulty in predicting failure limits the use of braided composites in industrial applications. Structural health monitoring (SHM) is a technique which integrates sensors in advanced engineering structures. The addition of SHM sensors within braided composites will help to increase industrial adoption of braided composite structures.
In this project, the student will integrate health monitoring sensors within braided composite structures. Conductive carbon fiber yarns will be incorporated into composite braids to perform health monitoring. Experiments will be required to validate the integrated health monitoring sensors accuracy and repeatability.
This work will involve the fabrication of conductive carbon fiber yarns for integration within braided structures. Mechanical testing will be required to validate in-situ strain measurements for braided composite structures.
Duties and Responsibilities of the student:

  • Fabricate and test sensors integrated in a braided structure
  • Plan, carry out and analyze experiments
  • Follow safe lab procedures
  • Read relevant literature
  • Present research results in regular meetings
  • Write up results to be submitted for publication or to be part of a future publication

Skills and Qualifications:
Working knowledge of chemistry to treat carbon fiber yarns for health monitoring would be beneficial but can also be learned during the summer or in preparation before the start of the summer.
